Los Gatos HVAC work starts with the town itself: steep lots, older estates, and a summer climate that can swing from fog-cooled mornings to 90-degree afternoons in the same day. As Cold Harbour Heating and Air San Jose, we serve Los Gatos with a straightforward approach: a written price before any tool leaves the truck, a firm arrival window, and every repair backed by our 365-Day Done Right Promise in writing. If you’re researching an HVAC company in Los Gatos, the key is finding one that understands hillside ductwork and won’t surprise you at the door. Call (669) 800-4179 and a live person answers, day or night.
Why Los Gatos Homes Are Different
Los Gatos sits in a warm-summer Mediterranean pocket where the valley floor, shaded canyons, and exposed ridges each run their own temperature. We regularly see a ten-degree spread between downtown and the hills above Highway 17. That means a cooling system sized for a flat ranch on University Avenue will strain on a west-facing custom home up in the Kennedy Road area.
The housing stock compounds it. Downtown Los Gatos has early Craftsman and Victorian homes with original framing and, often, heating systems that have been patched rather than replaced. The flats hold mid-century ranches with ducts that were run decades ago and never meant for modern heat pump airflow. Then there are the hillside estates: split-level layouts, finished lower floors, tight attic access, and remodels that added square footage without resizing the mechanical room. A technician who misses the ductwork behind the wall will never get the airflow right, no matter how good the equipment is.
Permits and HOA rules are a real part of the job here too. Some hillside neighborhoods review exterior condenser placement for visibility and noise. We’re used to working with the town’s building and planning process so the system is comfortable, compliant, and quiet.
Styles & brands we work with
Our Main Los Gatos Services
The two services Los Gatos homeowners call about most are air conditioning repair and furnace repair, with installation close behind as systems reach the end of their life. Here’s how each one works in Los Gatos specifically.
AC Repair in Los Gatos
Most cooling calls here come on the third or fourth consecutive hot afternoon, when the temperature hits the 90s and the system can’t hold 78. In Los Gatos, that often traces back to a refrigerant leak, a failing capacitor, or a condenser buried under oak debris from the fall. Hillside homes add a second layer: airflow problems from undersized or poorly routed ducts. We diagnose the whole system, show you the failed part, and give you a written price before we touch it. Every repair is covered for 365 days. If it fails, we come back and correct it at no charge. See full details on AC Repair in Los Gatos.
Furnace Repair in Los Gatos
Los Gatos winters are mild compared to the East Bay or Tahoe, but the cold season still brings wet, damp days with overnight lows in the 30s. Furnace failures here often show up as short cycling, a dirty flame sensor, or a blower motor that’s finally given out. Older downtown homes have gas furnaces that deserve a real diagnosis before anyone tells you to buy new. We stock common parts for Trane, Lennox, and Goodman systems so many repairs are done in one visit. Our repair comes with a written 365-day guarantee, and the price is on paper before we begin.

AC Installation in Los Gatos
When a Los Gatos system is beyond repair, the right replacement isn’t a guess and it isn’t a copy of the old unit. We do a full load calculation, check the ductwork, and size the system for the house as it exists now, not as it was built. For hillside and split-level homes, that often means a more flexible air handler placement and a high-efficiency heat pump. Installation is quoted as a fixed written price, with no day-of surprises. See AC Installation in Los Gatos for the full scope and local pricing.

AfterPricing for HVAC Company in Los Gatos, CA
Los Gatos HVAC pricing follows the terrain and the housing stock as much as the equipment. Here are the ranges we quote for common work in this area:
| Service | Typical range in Los Gatos |
|---|---|
| AC repair, general | $150 – $650 |
| Furnace repair, general | $150 – $700 |
| AC installation, full system | $3,500 – $7,500 |
| Furnace or AC tune-up | $80 – $200 |
What pushes a Los Gatos job toward the upper end? Usually access. A split-level hillside home with a tight crawlspace or an air handler stuffed into a finished closet takes longer to work on than a flat-lot ranch with an easy mechanical room. Also, older ducts and remodels add diagnostic time, and multi-zone systems have more components to test. No matter the range, you always get the written price before work starts, and it doesn’t change at the door.

FAQs About HVAC Company in Los Gatos
Most Los Gatos calls get a technician dispatched the same day, including evenings and weekends. The live person who answers the phone checks the schedule right then; hillside roads may add a few minutes, but we give you the arrival window when you call, not after.
It depends on the neighborhood and the scope. Exterior condenser swaps in some hillside HOAs require design review, and full system replacements need town permitting. We handle the paperwork for you and coordinate with the town’s building department so nothing stalls the project.
